Product Description P/N: AFX24-SR
Description
The Belimo AFX24-SR is an electrically powered, spring return damper actuator for modulating airflow control in commercial heating, ventilation, and air conditioning systems. It provides 180 in-lb of torque, accepts a 2–10 VDC control signal, and returns the damper to its configured fail-safe position when power is lost.

Information About AFX24-SR
The AFX24-SR is part of Belimo’s AF series of fail-safe rotary actuators. Its direct-coupled construction uses a universal clamp for attachment to compatible damper shafts. A microprocessor-controlled brushless motor provides positioning and electronic overload protection throughout the operating range. The actuator interfaces with compatible electronic controllers and supplies an analog position feedback signal for monitoring.
Key Features:
- Modulating operation: Positions the damper in response to a 2–10 VDC command.
- Rated torque: Delivers 180 in-lb / 20 Nm for compatible damper loads.
- Mechanical spring return: Moves the damper to its fail-safe position following loss of power.
- Low-voltage supply: Operates from nominal 24 VAC or 24 VDC power.
- Position feedback: Provides a 2–10 VDC output for actuator position indication.
- Reversible installation: Supports clockwise or counterclockwise fail-safe action through mounting orientation.
- Manual positioning: Includes a hex crank for adjustment without powered operation.
- Adjustable travel: Provides up to 95° rotation with a mechanical end stop.
The AFX24-SR delivers the reliability and precision required for proportional airflow regulation and fail-safe damper positioning in commercial ventilation systems.
